Abstract:
An interior permanent magnet motor includes a stator having teeth on which a coil is wound, a rotor rotatably provided inside the stator, the rotor including a plurality of rotor sectors, and at least two permanent magnet recesses formed between the rotor sectors. Ferrite permanent magnets are embedded in predetermined ones of the permanent magnet recesses that are formed in an inner portion of the rotor. Rare-earth permanent magnets are embedded in the other ones of the permanent magnet recesses that are formed in an outer portion of the rotor.
